CAR-VENTILATO R.

SPECIFICATION forming part of Letters Patent No. 277,903, datedv May 22, 1883.

Application filed May 11, 1882.

the following is a specification, reference being had to the accompanying drawings and letters ofreference marked thereon, in which- Figures 1 and 2 are views of a section of car-b0dy having my device attached; and Fig. 3 is a view of a car having my device attached, illustrating the best method of application. The air box in Fig. 1 is shown in section through the plane indicated in Fig. 2 by the dotted line w x.

The object of my invention is to provide a cheap and efficient means of changing the air in a moving car, it being more especially designed for smoking-cars; and I accomplish the object of my invention by the device herein described, and illustrated in the accompanying drawings.

c is a wind-wheel having arms whose faces are at an angle, as shown, whereby the wheel is caused to revolve if the air come forcibly in contact with the arms, as will be the case if the device be attached to a moving train of cars. This wheel is secured to the shaft h, which has bearings in the hangersf, and these hangers are secured to the car by bolts 23. The shaft g has bearings in the sides of the air-box a. The gears e and d are secured to the shafts in the position shown. The airbox is fastened to the car, by screws, bolts, or other convenient means,at' a point opposite an opening in the car-body, and a register is provided to control the current flowing into the air-box.

b is a fan secured to and revolving with the shaft 9 within the air-box. A portion of the air-box is contracted, and is provided with a cap, it, which revolves on the part of the box marked it. The cap is provided with an outlet tube, I, and a thin piece, '6, which piece, coming in contact with the air when the car is in motion, serves to turn the cap to such position that the outlet-tube will project in a direction opposite to that in which the car is moving. The revolution of the fan b draws the air from the car and forces it out at the outlet-tube. The fan-shaft receives its motion (No model.)

through the medium'of the gears, and motion is imparted to the gears by the wind-wheel c.

The fan b may be attached, if desired, directly to the wind-wheel shaft h, the position of the parts being varied for that purpose, and the intermediate machinery be thus done away with. I deem the arrangement shown, however, the best, as the comparative speed between the windwheel and fan may be varied by varying the intermediate gears. More than one device may be attached to one car.

I deem one, however, suficient, and if it be desired to exhaust the air from more than one point in the car, then I provide the exhaustpipesj, which may be connected with any part of the car. I I deem it best to attach the device to the bottom of the car, as illustrated in Fig.3; or it may be attached to the sideor top; or the wind-wheel may be attached at one place and the air-box and fan in another, suitable means being provided to communicate the motion from the wind-wheel to the fan.

It willv now be seen that, if the device he attached in the manner shown to a moving car, the air will come in contact with the blades of the wind-wheel and cause the wheel to re- I Patent, is-- 1".- In a car-ventilator, an air-box, a, having a contracted air-exit, provided with a revolving cap, it, and having a fan, I), combined with the wind-wheel c and shafts It and g, p'rovided with gears, whereby the motion of the wind wheel is communicated to the fan, all con structed and operating substantially as shown.

2. In combination with a ear, an air-box having a fan adapted to revolve therein and draw the air from the carinto the air-box, and provided with one or more pipes,j, communicating with the interior of the car, and a windwheel having a means of communicating its motion to the fan, constructed and operating substantially as shown.
